Yeo Wonyoung hands you over a huge tip for being the best server, and because she thought you looked cute. It was a way of saying thank you. She could just simply give you more, but she didn't want to get too attached too quickly when she just met you.

Once she handed you over the tip, she simply gave you the brightest smile. Her smile was warm, and there wasn't anything scary about her. She really did look like a friendly customer with that bright smile on her face.
